Exhaust & Emissions

What is the Purpose of the Exhaust System?

The exhaust system has three major functions:

  1. To direct harmful waste gases out of the vehicle.
  2. To reduce emission in the atmosphere.
  3. To reduce exhaust noise.

Important Components and Functions in the Exhaust System

  1. The PCV valve controls the internal pressure in the engine and causes the engine to run rough when not in good condition.
  2. The catalytic converter reduces the overall exhaust emissions released into the atmosphere.
  3. The EGR valve reduces the amount of harmful nitrogen oxide released into the atmosphere.
  4. The oxygen sensor monitors the amount of unburned oxygen in the exhaust system in order to gauge the fuel mixture.
  5. The muffler reduces the overall noise of the exhaust.
